EFFECT OF BIO-FERTILIZERS ON SOIL AND PLANT MACRONUTRIENTS AND TOTAL MUNG BEAN PLANT PRODUCT.
Main Article Content
Abstract
fields (alternative site in the Abu Ghuraib) for season 2016, three types of
bacterial isolates are: Rhizobia legumenosorum, Pseudomonas fluorescens and
Bacillus megaterium, seeds were contamination with inoculum, after a few
minutes seeds were planted, field experience designed according to (RCBD) , the
synthesis of bacteria without fertilizer formulations, synthesis with 0.25 fertilizer
formulations
(R.,R.+B.,R.+P.,R.+B.+P.)
and control (100% fertilizer
formulations only), after 70 days from the cultivation (N,P,K) was measured in
plants and the remaining in the soil after harvest , the results was showed that
the treatments of bio-fertilizer was significant superiority in Percentage of the
three main elements (N,P,K) absorbed from plant comparison with control that
recorded minimum value of these elements (0.99 ,0.32 , 1.56) %, while MBP25
treatment have recorded highest percentage of, the three elements (N,P,K) (1.59
,0.77,2.03 )%, significant superiority on control and double treatments, the three
main elements (N,P,K) available and residual in the soil after harvest in all
treatments was significant superiority to control ,the MBP25 treatment was
highest percentage of these elements (152.7 , 24.6 , 230.6 ppm) and MB25 was
followed ,in total yield MBP25 were superiority on other treatments in yield
(1211.2 kg.ha-1) , plant height (65.8 cm. plant-1).
